Fig. 3 represents a fragmentary scribed. l/Vithin the casings 9 are mounted plan view of one of the propelling-shafts and screw-propellers 11, said screw-propellers bea valve and its operating mechanism mounted ing retained within said casing by means of bars 12. (Shown in Figs. 6 and 7.) Said bars 12 provide means upon Which the shafts 13 are journaled, said shafts 13 extending through the casings 9 and the compartment 2 into the main portion of the vessel and are provided at their inner ends with suitable beveled gear-wheels 14. The shaft 13 is mounted at its inner end upon a suitable standard 15. The beveled gear-wheel 14 is loosely mounted upon the shaft 13 and is always connected with the adjacent gear-wheels,and said wheels are provided with a beveled wheel 16, which is connected with the motor or any other suitable driving mechanism and which imparts motion to the said beveled gearwheels 14. Upon the upper portion of the standard 15 is mounted a lubricating device 17. If it is desired to rotate a particular shaft, it will be necessary to slide the annular clutch-sleeve 18 upon the shaft 13 by means of the lever-arm 19, and the said member 18 is adapted to engage the beveled gear-wheel 14, and thereby actuate the shaft 13. By this construction I can simultaneously operate all the shafts carrying the propellers, or it is desired to have only one shaft and propeller in operation by throwing the clutch mechanism this result can be obtained. It is obvious that one or all can be thrown out of operation by the described clutch mechanism.

In this invention I do not claim any special motive power, as it will be apparent that the propellers can be actuated by a steam-engine or an electric motor.

The sliding valves 10 are mounted upon the tubular casings 9 near their discharge ends and are constructed by assembling upon the I casings 9 a box or casing 20, which is constructed of a plurality of parts and is retained in a fixed position by any suitable means. Within this casing 20 is slidably mounted a valve member 21, which is provided with means for manually sliding the same. Upon the casing or compartment 2 is formed a recessed portion 22. Upon the shafts 13 are mounted rotary valves 23. These valves 23 are constructed by assembling therewith a tubular shaft 24, which is screw-threaded upon its periphery, and upon one of the faces of the valve 23 is mounted a packing 25, which is secured in its normal position by means of a sleeve or plate 26, said plate being retained in an assembled position upon the valve member 23 by means of bolts 27 or like means. In the drawings I have shown said members 23 provided with an annular hollow projection 28. Within said projection 28 is suitable packing which is adapted to engage the shaft 13. Upon the casing of the compartment 2 is formed an annular hollow casing 29, within which is mounted suitable packing. Upon the casing forming compartment 2 is an arm 30, extending therefrom, which is provided with means whereby the actuation of the hollow cylindrical sleeve 24 is controlled. If it is desired to close one of the openings 31 formed upon the secondary casings 9, it will be necessary to rotate the wheel 32, which imparts motion to the longitudinal shaft 33, carrying a plurality of worm-wheels 34. These wheels 34 are adapted to engage gear-wheels 35, mounted upon the valve-shaft 24. The said gear-Wheel 35 is slidably mounted upon shaft 24and is provided with an extension which engages a longitudinal groove formed upon said shaft. If it is desired to actuate only one of the rotary valves, it will be necessary to throw the others out of engagement with the operating mechanism, and this result is obtained by pivoting the lever 36 upon its fulcrum, and thereby moving the worm-wheel 34 longitudinally upon the shaft 33 until the said wheel 34-is out of engagement with the gears formed upon wheel 35. It will be obvious that by this mechanism for controlling the valves mounted upon the shafts 13 one or all can be operated, and if it is desired the ends 31 of the tubular casings 9 may be closed.

Each of the compartments is provided with waste-pipes 52, whereby the said compartments may be drained when all the valves are in a closed position, thereby forming an air or Water tight compartment.

By the projections 22, formed upon the casing or compartment 2, a recessed portion 22 is formed upon said casing and in which the valves 23 are normally retained. By retaining said valves 23 within this recessed portion of the casing they will be entirely removed from the path of supply as the water or the like is supplied to the propellers 11.

The casings 9 are provided with removable covers 37, being retained in a fixed position upon said casings by any suitable fastening -means. Upon the primary casing or compartment 2 is also mounted a hinged or removable cover 38. By the construction of the casings and the arrangement of the valves it will be apparent that any one or all of the same may be closed, and by removing the covers access to the interior thereof will be obtained. In the event of a propeller becoming disabled it will not be necessary to stop the progress of the ship, but only the operation of the particular propeller, and by closing the valves, as heretofore described, examination of the particular compartment can easily be made.

A lubricating device 39 is mounted upon the extension 30, which is formed integral with the casing 2.

In Fig. 8 the propeller-shafts 13 are arranged in parallel position, and instead of employing the bevel-gears 14, as is shown in Fig. 1, I employ gear-wheels 14 for the purpose of imparting motion to the propellers. The compartments or casings, as shown in Fig. 8, are arranged in parallel position and are so constructed as to discharge the water which is passed through the same into a common compartment 50, which is provided with ITO an opening 51 at the stern of the vessel. The propeller-blades, as shown in Fig. 8, are not provided with a central shaft or reinforcing portion extending the length of the same, as shown in Fig. 1; but the said propellers are provided with a screw-blade, which is secured to the shafts 13, at one end thereof. The detail construction of the compartments in this modification is practically the same as that heretofore described for the construction of the device shown in the other figures of the drawings.

It will be seen that upon the closing of the valves 10 at the ends of each of the parallel casings containing the propellers the said compartment formed by'the closure of said valve 10 will prevent any water from passing through the closed compartment. It will be apparent upon considering the specification and drawings that the valve 8 can be so arranged as to control the inflow of the water into the compartments containing the propellers.

In the construction described it will be apparent that I have provided means for actuating all of the shafts carrying the propellers simultaneously; but, if it is desired, any one of said shafts may be thrown out of operation by the clutch mechanism. If it is necessary to examine any or all of the compartments containing the propelling means, I have provided means whereby accomplishment of the same can easily be obtained.

In the construction of the device if it is desired to provide a casing 11 extending the entire length of a ship this can be accomplished by connecting the said casing with a port near the bow of a vessel and extending the same under the propelling means to the primary casing 2. I have shown in Fig. 1 in dotted lines this proposed embodiment of the invention and have also disclosed a valve 10 (shown in dotted lines) therefor.
